BOTTlNG APPARATUS.

Application filed November 9, 1925. Serial No. 67,775.

erated means for withdrawing the betting bar out of the tuyre.

A further object is to provide a botting apparatus having 'the novel combination, construction and design of parts `hereinafter described and illustrated in the accompanying drawings.

In the drawings:

Figure 1 is a' sectional elevation througha portion of a blast furnace wall showing the botting apparatus in elevation.

Figure 2 is a rear elevation on the line Il-II of Figure 1.

Referring more particularly to the drawings, the numeral 2` designates the furnace wall having a' cnder notch tuyere cooler 4 mounted in the cinder notch opening. Y

A suitable overhead'support 5 extends outwardly from the furnace and is suspended by a band 6 from the bustle-pipe 7 of the furnace.

A pair of shaftsS and 9 extend transversely through the support 5 with their ends projecting beyond the sides of the support, and four relatively short links or arms 10 are provided, one of which ismounted adjacent each shaft end. A second pair ofV shafts 11 and 12 are journaled in bearings Y support.

links or arms 13 on the bottom of the support 5 and have their ends projecting beyond the sides of the yFour additional relatively short 14 are provided and one is ixedly mounted adjacent each of the ends of the shafts 11 and 12.

A pair of relatively long linksl are pivotally connected to a botting bar 16 inter-V mediate its ends at 17, and are pivotally connected intermedia-te their ends at 18 to v' fluid is permitted to -escape from the cylinthe links or arms '14 carried by the'shaft 11 and at their upper ends as at 19 to the links or arms l0`c'arried by the shaft 8.

A second pair of relatively long links 20 are pivotally connected to the botting bar 16 tuyre 3 and adjacent its rear end at 21 and are pivotally connected intermediate their ends at 22 to the links or arms 14 carried by the shaft 12 and at their upper ends as at 23 to the links or arms 10 carried by the shaft 9.

The upper ends of the links are connected to the upper ends of the links 2O by tie and control links which are pivoted to the links 15 at the pivot point 19 and to the links 20 at the pivot point 23. The link 2Oa maintains the upper ends of the links 15 and 20 in horizontal alinement and causes a uniform movement thereof.

. A counterweight lever 24 is iiXedly mountplane during a swinging vertical movement to withdraw or enter Vthe bar into the tuyre.

The bar 16 has a tapered head portion 26 adapted to snugly fit in and close the opening in the tuyere 3. l

The botting bar 16 is adapted to be withA drawn from the tuyre 3 byl a cable 27 having one endsecured at 28 to the bar and trained over sheaves 29 and 30 on a support 31 and having `its other end connected to the plunger rod 32 of a Huid pressure cylinder 33.

In operation when iuid pressure is admitted to the cylinder 33 the plunger rod 32 will be moved-downwardly and pull on the cable 27 so as to tend to move the rear end of bar 16 rearwardly.y and upwardly, but the upward movement of the bar will be resisted by the links or arms 10 and 14 and the whole 'bar will be compelled to move rearwardly and upwardly whilethe bar is maintained on ahorizontal plane. The upward movement of the bar isnegligible dueto the vnovel link arrangement,during the iirst part of-its rearward movement and during the last part of itsforward or entering movement so as to permit the head 28 ofthe bar to leave or lenter the tuyre without binding.

When it is desired to close the tuyere the der 33 and the counterweight 425 will rock y'the shaft'12 so las to move. the bar forward iorm of my invention, it will be understood that I do not wish to be limited thereto, since various modiiied constructions may be made without departing from the scope of my invention as deined in the appended claims.

l claim:

l. rThe combination with a cinder notch tuyere of a betting bar adapted to close said tuyre, an overhead support, two sets of links consisting of two pairs of links each, each of said links having a iixed pivotal connection at one end with said support, the pairs of links oil each of said sets being spaced vertically, two pairs of other links, each of said last named pairs ot links being pivotally connected adjacent their upper ends to and suspended from respective ones ot said sets of links first named and having theirY lower ends p'ivotally connected to said bar,

means for maintaining the upper ends of said last named links in horizontal aline' f ment to withdraw or enter said bar into said tuyre.

2. The combination with a cinder notch tuyere ot a betting bar adapted to close said tuyre, an overhead support, two sets oi' links consisting oif two pairs ot links each, each oi' said links having a liked pivotal connection at one end with said support, the pairs or" links of each of said sets being spaced vertically, two pairs of other links, 4each of said last named pairs ot links being pivotally connected adjacent their upper ends to and suspended from respective ones of said sets oi links first named and having their lower ends pivotally connected to said bar, means 'for maintaining the upper ends of said last named links in horizontal alinement, said links being so proportioned and assembled that they will maintain said bar horizontal during a swinging vertical movement to withdraw or enter said bar into said tuyere, and power operated means for swinging said bar rearwardly to withdraw said bar from said tuyre.

3. The combination with a cinder notch tuyere of a botting bar adapted to close said tuyere, an overhead support, two sets of links consisting of two pairs of links each, each of said links having a fixed pivotal connection at one end with said support, the pairs of links of each oi. said sets being spa-ced vertically, two pairs of other links, each of said last named pairs of links being pivotally connected adjacent their upper ends to and suspended from respective ones oic said sets of links first named and having their lower ends pivotally connected to said bar, means for maintaining the upper ends of said last named links in horizontal alinement, said links being so proportioned and assembled that they will maintain said bar horizontal during a swinging vertical movement to withdraw or enter said bar into said tuyre, power operated means 'for swinging said bar rearwardly to withdraw said bar troni said tuyere, and gravity operated means igor moving said bar forwardly into said tuyere.

4. The combination with a cinder notch gituyere ot a betting bar adapted to close said tuyere, an overhead support, two sets oi links consisting of two pairs ot links each, each of said links having a iixed pivotal connection at one endwitli said support, the pairs of links of each of said sets being spaced vertically, two pairs of other links, each of said last named pairs of links being pivotally connected adjacent their upper ends to and suspended from respective ones of said sets oil links iirst named and having their lower ends pivotally connected to said bar, connecting links extending between Vtwo upper ends of said last named pairs of links to maintain the upper ends of said links in horizontal alinement, all of said links being so proportioned and assembled that they will maintain said bar horizontal during a swinging vertical movement to withdraw o1` enter said tuyere, a power operated means oonnected to said bar tor swinging said bar rearwardly to withdraw said bar from said tuyre, and a coiinterweighted lever mechaiiism adapted to force said bar forwardlyV into said tuyre when said power operated means is released.

5. The combination with a cinder notch tuyre of a botting bar adapted to close said tuyre, a support, link members connected at one end to longitudinally spaced points of said bar, means forming a swinging pivoted connection between the other end of said links and said support, means for tying the upper ends of said links together so as to compel uniform movement thereor", both of said means cooperating'to compel the upper ends of said links to move simultaneously through duplicate segments of a circular path when a rearwardly and upwardly or a ldownwardly and forwardly directed force is applied to said bar, thereby maintaining said bar horizontal during a swinging vertical inovenient to withdraw or enter said bar into said tuyre, power operated meansY ALFRED osoLiN.
